Question

How do you find the x and y intercepts for `y= -4 - 4x`?

Answer 1

x-intercept `= -1`, y-intercept `= -4`

Explanation:

Intercept form of linear equation is `x/a + y/b = 1`

Given `y = -4 -4x`

`4x + y = -4`

`x/-1 + y / -4 = 1` is the intercept form equation.

x-intercept `= -1`, y-intercept `= -4`

Answer 2

`"x-intercept "=-1," y-intercept "=-4`

Explanation:

`"to find the intercepts, that is where the graph crosses"`
`"the x and y axes"`

`• " let x = 0, in the equation for y-intercept"`

`• " let y = 0, in the equation for x-intercept"`

`x=0rArry=-4-0rArry=-4larrcolor(red)"y-intercept"`

`y=0rArr-4-4x=0rArrx=-1larrcolor(red)"x-intercept"`
graph{(y+4x+4)((x-0)^2+(y+4)^2-0.04)((x+1)^2+(y-0)^2-0.04)=0 [-10, 10, -5, 5]}
